The SN75189D is a high-performance, monolithic low-power Schmitt trigger quad line receiver manufactured by Texas Instruments. This device is designed to meet the requirements of ANSI Standards EIA/TIA-232-E and ITU (formerly CCITT) Recommendation V.28. It is primarily used in interface applications and is designed to improve both the performance and density of three-state RS-232, RS-485, RS-422, RS-423, and other multipoint applications.
The SN75189D is characterized for operation from 0°C to 70°C. It is available in a 14-pin SOIC package, which is ideal for space-constrained applications. This device is designed to receive high-speed data streams and has a typical propagation delay time of 6 ns. It offers a wide supply voltage range from 4.5V to 5.5V, allowing it to be used in a variety of applications.
The SN75189D features a high input impedance, which makes it suitable for multipoint applications. It also has a low power consumption, making it an excellent choice for portable and battery-powered devices. The outputs of the SN75189D are designed to sink 24 mA and can drive a wide range of loads, including capacitive, inductive, and resistive loads.
The SN75189D also features built-in hysteresis, which improves noise immunity and transforms a slowly changing input signal to a fast changing, jitter free output signal. This device is also equipped with a three-state output control, which allows multiple units to be connected to the same bus.
In conclusion, the SN75189D from Texas Instruments is a versatile and reliable quad line receiver that offers excellent performance and a wide range of features. Whether you are designing a multipoint communication system or a high-speed data acquisition device, the SN75189D is an excellent choice.
